I picked up an F7 Tigercat with two DLE 30's in her. The engines are the older version with side mounted Tillotson carbs number on them is HU134A
I know the engines were run once then the plane was stored. I do not know if Ethanol fuel was used. Whenever I buy a plane with gas engines and don't personally know the history I will get a carb kit and change out all the perishable parts and give it a good cleaning, reset the needles to factory specs and fly happy.
When I searched for the Repair Kit RK31HU and GOOGLE led me to "Jacks Small Engines" Their site listed the kit in stock at a good price so I ordered 3 on 8/8. The order confirmation said that the kits were not in and that the order would ship on 8/16. Today I called to see if the kits were being sent and was told that they won't have them to send out until 9/5 at the earliest. Not good since the site gives the buyer the impression that this was an in stock item. I had gotten no emails from Jack's that these were back ordered.

I did order today from Amazon an off brand kit from Sunbelt Outdoor products that is suppose to be compatible with the HU carb series.

When these kits arrive I will disassemble the carbs and compare the parts. If anyone has alternate sources please post.

Thanks,
Pete
