As you will remember, I have said the bay was not itself when changing to the G-Tec ignition, and that a sluggish drive followed,
Then I found the distributor has wear and issues which where repaired and fixed.
Only did short drives after that and was under the impression it was sorted.
Well....
Had to take the Bay to Port Alfred to deliver some 6 m pipes in its roof rack, no, this is not an issues as she always does these jobs when needed.
So on the trip, the 1st hill out of Jefferys bay is a hell of a hill and she normally went up without speed lose.
How ever this time I had to change down half way up, but still no problem.
Driving the 245 Km trip she had more and more problems with the hills, but picked up speed easy on the down hills or flat parts.
Nearing Port Alfred she could not get up the hills in higher then 2nd gear, and the last hill just out of PA we had to go down to 1st.
On looking into the engine bay she would idle fine, no problem, but as you accelerate, she would start backfiring.
The higher the motor speed the more she would backfire into both carbs.
But on idle, no back fire.
can start her no problem, fires up 1st time, but will not accelerate without backfiring constantly.
After speaking to my motor gurro, he said its timing, so I removed the G-tec, fitted the old Distributor with points and condenser, same thing.
Fitted the other distributor with built in electronic ignition, same thing.
Set tappets again, no change, disconnected carb link and accelerated each carb by it self, same thing.
Fitted new plugs, same thing.
Now my theory is that the backfire has to come from one valve being open when the spark fires, so as to ignite the fuel in the manifold so as to backfire into the carb.It can not fire into the manifold if there is no point of ignition.
Now you ask what did you find Herman, well.... nothing as I had to get her home 1st to be able to work on her.
So this Friday I went down early, when the sparrows where still clearing their lungs from last nights bad city air, and drove to PA
Fitted the 'a' frame and towed her back with the Fleetline.
Now I must remind you the Bay does not like being "A" framed and does not behave well having broken free from the towbar once before.
So the trip was a cool 4and a half hour return trip but she is safely home without incident.
Will pull her into the workshop and do a compression test and see if there is a chamber problem, then the other possible issues will be looked for one at a time.
Any ideas what it could be ?????????????
Well till later, here are a few photos of the recovery trip.
