Chrishoughton1989 Posted February 11, 2013 Author Share Posted February 11, 2013 Is it not possible to set it using the marks on the cam ? On the dizzy end. Thanks. Quote Link to post Share on other sites
turbo Grant Posted February 11, 2013 Share Posted February 11, 2013 You can put it on close to your position of how your one is so it would run. But I wouldn't boost it till you have checked the timing with a timing light gun Quote Link to post Share on other sites
Chrishoughton1989 Posted February 11, 2013 Author Share Posted February 11, 2013 So if i look on old head and position how it was? That will be ok until I get it checked ? Quote Link to post Share on other sites
rmsnoel Posted February 11, 2013 Share Posted February 11, 2013 Short answer chris, no. I could bridge the pins and set my idle at 750_770rpm because I kbow ive no vaccum leaks and my throttle is set spot on but u are fitting a new engine. A timing light is 20quid or ask around, someones dad always has one. My timing light is 36years old and Im 29.You will use it again if you have it, 20quid is cheaper than than a cracked piston. Search how to set base timing. It 10° btdc on a warm engine with check pins crossed using a paperclip. Then when all timing is right you can set your throttle idle screw. Always check tps switch because its a on off type instead of the newer dimmer switch type. Quote Link to post Share on other sites

mech5107 Posted February 12, 2013 Share Posted February 12, 2013 Just a side note, I've seen that retarding the ignition to about 6 degrees, i gain a lot in mid range... and not actually loosing at high rpm... Quote Link to post Share on other sites

You would net more torque lower down the rev range, but it will suffer top end, which is where maximum ignition timing works best. You would be best off seeing what it does on the dyno, but every engines different. Quote Link to post Share on other sites
