I pulled the dist. myself, advanced a tooth & checked all the wires. Set it about where I thought it shoud be & fired right up! Adjusted the initial timing to 20 BTC. Still breaks up at full throtle, not as bad but still there. Wierd thing is now it also wants to stall when in gear & had to adjust the idle screw in more to get it to igle at 1050 in park & 850 in gear. Usually when advancing the timming the idle goes up & you have to turn it down.
