This Ciuouient kit includes two different rubber sealing gaskets and a plated exhaust adapter designed to fit a wide range of Stihl models. It’s built for shop use or field testing when you need to evaluate exhaust flow, backpressure, or confirm sealing after replacing mufflers, gaskets, or studs.

What Stihl models will this exhaust test plate work with?

The Ciuouient test tool is sized to match common Stihl two-cycle exhaust ports. It covers many popular consumer and professional saws, making it a versatile addition to toolkits that service multiple models.

• Compatible model list includes: Stihl 024, 026, 028, MS260, 034AV, 036, MS360, 038, 044, MS440, MS441, 046, MS460, 066, MS650, MS660.
• Fits UP591 chainsaw exhaust patterns and many concrete cutoff saws.
• Two gasket shapes ensure a snug seal across different flange geometries.

How do the two rubber gaskets improve testing accuracy?

Providing two distinct rubber sealing gaskets lets you match the gasket profile to the exhaust flange for a tighter seal. That reduces leaks that could mask actual pressure or vacuum readings, giving you more reliable diagnostics without improvising with rags or putty.

• Two gasket shapes accommodate varied flange contours and bolt layouts.
• Durable rubber resists fuel and heat exposure during short tests.
• Quick gasket swaps let you test multiple saws without modifying parts.

What tasks can I perform with the Ciuouient exhaust test plate?

The tool is intended for functional checks and adjustments of the exhaust and related systems; it streamlines checks after maintenance or when troubleshooting performance issues. Use it to confirm exhaust sealing, measure backpressure, or validate repairs before returning a saw to service.

• Seal exhaust ports for pressure and vacuum diagnostic tests.
• Verify muffler or gasket replacements seal correctly.
• Assist in tuning or troubleshooting by isolating exhaust-related problems.

How do I use the test tool safely and effectively?

Install the plate and the gasket that best matches the flange, secure the assembly, then carry out the diagnostic test with your pressure/vacuum gauge following manufacturer safety steps. Do not run prolonged engine tests while sealed; the kit is for short diagnostic checks and adjustments.

• Select the gasket that provides the best edge-to-edge contact with the flange.
• Ensure mating surfaces are clean and bolts are snug but not over-torqued.
• Use brief test runs and proper ventilation; avoid extended sealed operation.
