No Power and backfire
 

I have a 71 type 1 with a stock 1600 cc and a Bocar 34pict-3 carb. I
thought I had everything adjusted well. Today it started a little
backfiring and losing power after it was warm. When I take off from a
stop, or try to go up my driveway, it feels like there is no gas or
something, and then some soft pop, not a huge bang, but a backfire. I
dont have a steep driveway, but it took me 3 tries to get up it. I
turned the mixture counterclockwies and it did not seem to help. It
still just bogs out and pops when I give it gas. Any Ideas?

Thanks in advance,
John

Sounds more like a timing/advance problem.

I'm not sure what you mean by dual vac.

>From what I've been reading it does sound like timing. Would that go
overnight? Another thing I'm considering is it may be lower octane
gas. I may just get my Muir book out and do a Valve/timing/ tune up.
I think I'll try some premium gas first and see what happens. Easiest
and cheapest step first.

Thanks,
John

I'll check tonight. I've been reading the Muir and Bentley books today
and getting some good info from them. I see my kids playing with their
legos. This car is like that. The major difference is that my wife
dosen't get ****ed when the kids want to play with legos for an
afternoon.

Good.

Verify that they both work.
Suck on each hose and watch the advance plate.
It should move to the stop in each direction and stay there.

If it passes that test, check the initial timing.,
You *must* use a strobe light. The throttle must close fully
and the vac hoses left on. Timing is set at 5 degrees **AFTER** TDC!

Yesterday I adjusted the valves to .006 and regapped the points, using
my new dwell meter. It may have been the points because it now runs
like a different (very happy) car. I'm going to go ahead an check the
timing and pretty much go over everything. It seems the original issue
resolved.

I'm sure the more I do the more questions I'll have.

Thanks for the help.
