hi guys,
I recently replace my 4.3l block with a 02 blazer block cause the old one was cracked i put everything back to gether it started fine i did the TDC. it would idle fine but wont go over 2200 rpms i taught the carb was messed up caused this boat was sitting for a while so i baught a remanufactured carb put it on and it did the same thing so i lossen the distributor clamp and turned it a little and the motor idle changes significantly runs much smoother i took it out and ran it. Runs fine gets up to 4500 - 4700 rpm and then suddenly it drops out like its going to shut down went u let off the trottle it picks up back a little but u have to bring it down to idle the in about 30 sec you can peg the trottle again it will run good for a bit the does the same thing again. when i did tdc i align the tip of the router at # 1 cylinder pug lead on the cap. i was told that the timming is off and that when i put the distributor in it needs to sit just before #1 like closer to 2 so it fires on 1 when it rotates.
Can any 1 advice please very frustrated
thanks
