Hi Everybody
I realize this site is for type 3 VW enthusiast but I thought you might
be able to give me some advice.
I have a old home built trike with a 1972 type 3 fuel injected engine
with manual trans. The Trike ran good for about 2 yrs. Buy I had to store it
covered over outside for a month and when I got back, It would not start. I
got it started but now the engine is backfiring. It seams to run good when
you are heavy on the throttle but when you hold it at a steady speed, like
30 mph and just give it enough fuel to hold that speed the engine will
backfire continually, always from the same side muffler.
I have changed the spark plugs, plug wires the upper and lower points
and coil replaced the brain unit for the fuel injection. I'm thinking it may
be a bad fuel injector since it always backfires from the same side
exhaust. Any suggestions will be appreciated.
Thanks
Bill
Doyle
