Generator Propane Conversion
We decided to attempt a generator propane conversion, after seeing what happened after hurricane sandy, we decided it was for the best.
We finally received the conversion kit in the mail the other day and decided to attempt it.
this is the company we ordered our kit from, they were very helpful and e-mailed me several times for clarification on what we needed
biggest question they had was the make and model number for our motor, we have a husky with a subaru engine, the model can be found on the tag on the side of the engine, as you can see on the bottom of the tag we have a robin ex30
we started by using the regulator for the engine and marked out mounting holes for it
and then drilled them out
we removed the air filter cover
and the air filter itself
we opened the bag of supplied parts
and started putting together the carb adapter
We bolted down the regulator onto the frame through the holes we had drilled out
we screwed down the engine inlet onto the regulator and the propane feed line onto the regulator
we removed the mounting bolts for the air filter and replaced them with the supplied spacer bolts for the carb block and mounted that
we tried remounting the air filter assembly over the block but with the increased space we could not clear the down tube of the genny, I looked at my dad and said we need to cut the down tube, he responded no we don’t want to do that, we will just trim the air filter , so my dad broke out his roto tool
and he trimmed out the outer edge of the air filter to give us clearance
with the air filter housing trimmed we were able to fit it onto the carb block
we remounted the vacume hose onto the air filter
and connected the gas line from the regulator to the carb block
we screwed down the tank regulator onto the tank hose
and connected the hose to the engine regulator
since the spacing was so close with even cutting out the air filter we could not attach the air filter cover
so we popped the air filter in place and used a rubber band to hold it in place
we hooked up the propane tank
and we were ready to fire it up
to start the genny on propane you turn the gas on the tank and there is a prime button on the back of the regulator to drain the air out, you can see it here right above the brass fitting
our first firing
my father was adjusting the set screw in the front of the regulator trying to get the right air/fuel mixture
we started messing with the tank and was able to get a good fuel mixture by almost turning down the propane feed and we were able to get it running perfectly with playing with the tank, something still wasn’t right
we reread the manuals and couldn’t find anything, well actually we did, remember when I said we needed to cut the down tube?
my father doesn’t want to talk about this
anywho, my dad hopped on line and found out he was adjusting the wrong thing, the set screw in the front of the regulator isn’t it
it’s the brass t-fitting on top with the bolt and the lock nut on it,
once you get it running you loosen the set nut and adjust the bolt till you get it idling where you want to, you then tighten the lock nut to secure the setting. We adjusted that and now it purrs like a kitten. Also make sure you run it with the choke set to run not start.
We went with the dual fuel kit so we would still be able to run gas as well as propane. The price was only 30 dollars more I believe but if you go with just propane you have to tap into the carb so you couldn’t go back to gas without buying a new carb. Any questions fire away.
