Wrong diaphragm in carb kit

[Chris J.]

I've started my Jonsered 90 project saw. Earlier tonight I was installing a carb kit on the Tillotson HS. I saved installing the main diaphragm until the last, only to find out that the guide & screw holes in the kit diaphragm don't match up to the carb. Yes, I should've checked all of the pieces before I installed anything. In the kit the main diaphragm & the gasket are separate, & the gasket matches the carb just fine. The one that I removed from the carb is one piece, maybe original. I have 2 kits, so I checked the 2nd one--same problem.

Has anyone had any recent experience with bad carb kits? I'm wondering if there is something that I overlooked (a very real possibility), or are suppliers knowingly/unknowingly selling bad kits? I purchased the kits from Manufacturer's Supply, part 38-3644, carb kit replaces Tillotson RK-23HS. I'm going to call them tomorrow, but I wanted to get some input here.

Any experiences, advice, educated guesses, & even half azzed opinions are welcome.

Thanks,

Chris Jones

Chris-

sounds like you got the wrong kit. I've installed literally over a thousand carb kits in the last fifteen years and I've only had one kit that had an error. Are these actual Tillotson carb kits you're using or an aftermarket copy?

 

[Chris J.]

Jacob, They're probably aftermarket

kits. I don't find a manufacturers name on the package, the instruction sheet, etc. Are the actual Tillotson kits marked? Another odd thing is the instructions that came with the kit show a diaphragm cover retaining screw & lockwasher, which isn't on the carb.

I did a lot checking on the net, & I believe that for the Tillotson HS, RK-23-HS is the correct Tillotson # for the full rebuild kit, & RK-17-HS is the gaskets only kit. If I'm wrong I'm sure that someone will correct me.

Jacob, who would you recommend as a good source for legit (or at least quality aftermarket) kits? All help is greatly appreciated.

Bailey's sells it. In their catalog they list it for a couple Husky saws, but it's an OEM RK 23 HS kit, $6.95. I should stock up, got 7 or 8 saws that use the HS carb.

Oh, Tillotson kits are marked with a big logo on the bag.

"RK" is "Rebuild Kit" with everything in it. We don't stock the diaphragm kit but I believe they start with "DS" Or "DK" for diaphragm set or kit.

Aftermarket stuff in this category is a chancy deal, OEM kits are not out of line at all so why mess with aftermarket.

Having correct diaphragm sent.

I called Manufacturer's Supply, & spoke with a guy (who gave his name as Roxanne-???). He checked the two kits that they offer, & sure enough the diaphragms are different. He searched their catalog, & had me go on-line to compare the diaphragm that came off the carb to the one they have has an individual part. That one looks right, & they're going to mail me 2 of them.

Thanks to Jacob, Chris B, & Nevadawalrus for your reponses. In the future I'll get the actual Tillotson kit from one of sponsors, & be sure to check everything first. Live & learn!

Carb kits

Just,per chance,is the correct kit #38-1544.I have had the same problem,in the past,which is why I have all these carb kits,that fit nothing I own.

 

[Chris J.]

Al, the main diaphragm in kit 38-1544

seems to be the correct one. I'm new at this--I didn't realize that there were differences in the HS kits, other than one is gaskets & diaphragms, & the other also has the welch plugs, inlet needle, etc.

This might be of help. The two diaphragms that mfgsupply.com are sending me are part # 38-3654 (one metering diaphragm only), which looks like a match to the one in kit 38-1544 that you mentioned. It also appears to be a match to the one that came off the carb (I certainly hope so). Their toll free # is 1-800-826-8563. Maybe you'll get to speak with "Roxanne."

Thanks to all, Chris Jones

They made good

I received the correct diaphragms from Manufactorers Supply on Wed of last week. I thought it only fair to mention that they did took care of this PDQ.

I only wish that Wyomingben on ebay was as quick. 2 1/2 weeks & still no chainsaw manual; 3 email inquiries & not a single response. Maybe I'm being inpatient. Me? Never. Update: The manual arrived today. My reference library is growing....
