Just picked up this Enticer 340 for my son. Was told it was a 79 or an 80 but not sure. It needs a few things so I'd like to be sure before ordering parts. Where would the year be stamped on it or would there be a decal anywhere common? It hadn't been run in awhile and the guy I got it from had rebuilt the carb but said it still will only run with the choke on. He said the carb was REAL dirty and that he wasn't able to "get it" completely clean and that I may have to have it sonic cleaned before it will function properly. I did a compression check and it had about 100 psi on the clutch side and 115 psi on the mag side. Edit: I just retested the compression and it has a little under 100 psi in each cylinder. 95 mag side and 99 clutch side. Verified it on 2 gages. I think it's supposed to be 120?
I sprayed a little Tri-Flow (Light oil like wd-40) down the plug holes screwed in the plugs, pilled it and it fired up momentarily. I saw that it was starting to pump fuel so I gave it another squirt in the carb and it fired again. Next I did it again and kept it running by continuing to spray the Tri-flow in the carb. In about 10 seconds it was running on its own with the choke full on. I let it warm up a bit then turned the choke off in which it idles for about 10-15 seconds and wanted to die. I choked it again and it came back to an idle, I held the track off the ground and rev'd it up, seemed a bit rich but did rev. I let it come back to an idle and it idles fine as long as the choke was on. Im thinking a set of new plugs and take another run at the carb? I'm sure I can find all of the carb settings on this site so that's how I'll set it up. Any other tips? compression seem a bit low? I'm going to check it again here to see if the rings maybe sealed up a bit after running it. Here's a picture of the sled below, again any help on the year would be great.
Thanks,
LM

looks to be an 80 from the hood. there is a way posted here with the serial # to id the year for shure but they where all pretty much the same in that era.
sounds like the 78 I have outside. we know it needs crank seals as they tested bad. most likely the same problem with yours.
as to the compression, it depends on the gauge sometimes. anything over 90psi, it will run and if it has not been run in awhile the rings will probably re-seat themselves to the cylinder. also it is air cooled and they read lower typically unless at operating temp.

Cleaning the carb now, can't figure out how to get the needle jet out. (the one that the main jet threads into).

He's vey happy for sure! I always wanted one of these sleds when I was a kid as several of the kids in my neighborhood had them. My dad wasn't into snowmobiles so that didn't happen. He did however one day bring home an old battle ship Arctic Cat one day that we rode when it ran. Usually by the time I got it started, I was too tired to ride it.
I got the carb done on this Exciter (never did get the needle jet out though) and it runs pretty good, actually better than the old Arctic Cat ever did and this thing is 33 years old. I'll probably re-ring it and replace the crank seals in time with my son so he gets some "hands-on". He already helps me with the race cars, but the engines are a bit too spendy to turn him loose with a wrench just yet.

its an enticer. make shure you check the crank seals before he blows it up from leaning out. the 78 outside has $800.00 into the motor and fuel pump rebuild without the crank seals. good thing the labour was done by my brothers high school tec class.
those are an awesome sled to learn on! we had a 79 250 and it was faster than most 340's.
