No spark after top end rebuild

[Fullsizechevy9]

Just finished rebuilding my 200s top end now i have no spark had spark before i did everything by the manual all connections are good anybody have any ideas?

Start with the pulse rotor. Make sure it's not 180 degrees outta time.

[Fullsizechevy9]

Could my pulse rotor air gap be to wide i set it at .018 book said .015-.025

[Fullsizechevy9]

Ill double check it but i did it exactly by the book flywheel on the f index mark lined the pulse rotor up with those index marks and set the air gap

[Fullsizechevy9]

I do remember before i took it apart i lined up the f index mark and the pulse rotor was ahead of the index mark a little and ran good

[Fullsizechevy9]

Im going to open it up and double check the timing and cdi did it by the book but obviously somthi g isnt right it had fire before no way somthing quit working that fast

Try removing the spark plug cap from the plug wire. Trim 1/4" or so off the end of the wire and put the cap back on. Sometimes the end of the wire gets worn and you can't screw the cap back on and have a good connection.

Did you try adjusting the cam chain?


ETA: Did you remember to put that little rubber plug in the head?

Def valves anybody have any suggestions ill have to take the motor out to re set the valves thats what im going to try next do i need to set them at honda specs or is there dif specs on the valves for a wiseco piston i couldnt fimd anything on it i set them at .002

[Fullsizechevy9]

Heres a video of the sound its a loud tick obviously coming from valve area im going to take the motor back out and see if i can get an indicator on the top of the piston and fimd tdc that way and reset the valves instead of relying on tbe index marks i think thats wjere i went wrong

It’s as simple as putting a screw driver in the spark plug hole to find TDC , cam lobes pointed down and set the valve lash . A few degrees either way isn’t going to make a difference .
The tick noise is probably a loose timing chain .

The tick noise is probably a loose timing chain .I took the cap screw out put a 3mm bolt in there and pushed down and pulled up didnt changed the noise its def coming from up top im going to reset the valve lash with a screwdriver or indicator instead of the index marks and see what that gets me is .002 the right clearance i wouldnt think the 10.25:1 piston would change the valve lash specs right

Sent from my SAMSUNG-SM-N920A using TapatalkDef not cam chain its just right has to be valve lash hopefully setting it without the index marks will do the trick if not ill be tearing it back down i didnt do the clay trick on top the piston but i did turn it over by hand and nothing was hitting that i could tell i doubt the piston is hitting the valves its def timed correct ill let yall know what happens

Ok guys valves were way to loose true tdc is a little ahead of the t index mark i should have done this to begin with but u live and you learn another problem im using a carb off a 200e and i have the idle back out all the way and its still idled to high the barrel is sitting all the way down in the carb the cable is good and isnt sticking idk what else could be causing it

Sent from my SAMSUNG-SM-N920A using TapatalkThanks for the help everybody i got everything squared away nothing like rebuilding somthing put all that time into in and realizing somthig isnt right my true tdc wasnt dead on with the index so that was my ticking problem got that solved tore the carb down started inspecting the cable more and the cap to the carb wasnt screwed all the way onto the piece that the cable slides through causing it to basically give it gas when i wasnt on the throttle i never checked it when i put it on lesson learned shes idleing awesome now and has so much more power and response its night and day difference i cant wait to get a cam bigger carb and better exhaust on it i will be extremely happy for what it is i love it nice and light can go just about anywhere and get it unstuck by myself good trail and hunting bike happy labor day i appreciate all the help it womt be the last time im.sure lolhttps://uploads.tapatalk-cdn.com/20190902/dd5ccff3102e269565079668651d193f.jpg

I also opened up the intake some mainly in the throat where the valve seats it has to kind of go around a lip so to speak so u opened it up made it more of a straight shot so the air can flow better and cleaned up the casting marks and i opened up the exhaust side pretty good made it more of a straight shot for the gases to go out and port matched my intake to head and carb to intake you would be surprised at the size differences making it harder for air to enter had probably 1/16 of a lip from carb to intake and also from intake to head which im sure slowed flow down a good bit between the high comp piston and the port job i did its a huge difference barely blipp the throttle and it just wants to go i use to have to smash it to take off fast
