Pretty much the title. 85 f150 I6 4x4 T19 will fure right up and pulls off great. Once you hit 45 its like you have hit a wall. I know NOTHING about propane engines/mixers but am willing to learn if someone can just tell me where to look. There are no propane mechanics in the area so if I have to do a rebuild kit on the conversion I will.

 

old thread i know that had no answer or post of the final outcome.
many propane conversions are found on industrial base engines , as when a motor is used in a stationary use like a pump or generator.use a rpm governor ,the governor is in the carb base,that may be the problem you feel ,

 

Interestingly enough, she is getting flatbedded tomorrow to a propane mechanic because I tried several times to fix this to no avail. Im hoping they dont mind teaching me something after bleeding me dry. Ill let you know if youre still intersted. I really appreciate the reply and ill be back!
