Gents,
I have an 1957 M52 with a holly carb on a gasser engine. This is Armyman30yearplus's old truck. Just did a run and for the first half (about 30 minutes) she ran fine at 55mph. After going thru tolls( slowed down, shifted,etc) i made the second leg of about 40 minutes. On this leg i could only get 45 mph due to backfiring and loss of power when pushing the pedal down. At 45 mph she runs steady with a slight hesitation at times and occasional backfire.
I had already planned on rebuilding the holly carb, and have the kit to due it. I am wondering if i should just buy a zenith and replace the holly? I have read that folks are happy with the zenith and was wondering if it is a true bolt on replacement? If the zenith really does get 4 mpg as opposed to 2 mpg on the holly - it will pay for itself on my first run!
I plan on using the truck to pull a 45 foot semi trailer hauling a ww2 M3 white half track and 2 ww2 british Dingo armoured cars. The main use will be making 4 hour over land runs to ww2 events.Having something for highway use was the plan. I went with the M52 for field recovery if needed , as it has a front winch. It is also a gasser , and righ tnow gas is cheap !
