Hi Larry ;
I finally got a moment to read your latest log , I'm concerned about your ignition timing ,you need to se the _total_ advance , not just where it seems to run well ~ this is simple if you have a dynamic timing light with advance dial on the back , I'm still using my 30 year old SEARS Craftsman one , most of my buddies have now purchased one either new or used for about $25.00 off E-Pay . Use the _triangle_ or _chevron_ that's faintly stamped into your flywheel as that's the TDC mark (you can wire brush it clean and drift some white paint into it for easy visability now the scatter pan is off) , warm up the engine and connect the timing light , I use rubber bands to hold the trigger on all the time and set the light where it'll illuminate the timing window , rev. the engine to about 2,500 ~ 3,000 RPMs and then set the dial to 35° , loosen the dizzy's pinch clamp and gently rotate it untill the triangle or chevron is aligned with the pointer and _stays_ when you release the dizzy , then snug up the pinch clamp . remember , the advance mechanism usually give you some slack so take your time to ensure the timing doesn't drift when you remove your hand . Too much ignition advance is very rough on the starter's Bendix and the ring gear too ~ it also beats up on the rod bearings..... If the starter begins to spin before the Bendix is fully engauged , loosen the two screws holding the starter switch to the starter and adjust it so the lever has to move a bit further before it makes contact and operates the motor . I'd remove the switch and _polish_ the contacts too ~ _NEVER_ sand nor scrape them ! . _YOU_ can prolly rebuild the starter better than any shop will , all it should need is : new brushes and bushings , cleaning and re- lubing . plus you won't chisel off and loose the original DELCO ID tag I see it still has . You mentioned a clunk when you release the starter , is the little retrun spring still on the pedal linkage ? it breaks often and is important to withdraw the Bendix rather than having the engine kick it out of engaugement . Before you pay over $25.00 for a good used flywheel , think about having the ring gear replaced on yours ~ there's two different ones with different tooth counts depending on 6 or 12 volt , if the machine shop cannot find a new one (doubtful) have them press it off and re-install it 1/4 turn in the direction the engine rotates , this will solve your engaugement troubles forever , an old dealer trick I still use . Billy Bob is looking good ! nice wax job . -Nate Larry wrote: > > For those of you who follow the BillyBob log entries, a new Work- in-Progress > log entry "Cab Capers and the D-train" has been posted.
